If you're looking to move up to a higher quality eyepiece the Omni Series provides more enhanced features in a wider selection of focal lengths. Celestron designed the series with the finer points in mind so you, the user, can benefit from the features that make this series unique.The 4mm high power Omni eyepiece is a 4 element, premium symmetrical Plossl optical design. Features include blackened lens edges to minimise internal reflection and maximise contrast, multi-layer coating group on each lens surface to maximise light transmission and contrast, and each Omni goes through a two-step anodising process to prevent reflection from the top eyepiece barrel, unlike most other manufactures that use reflective surfaces.

Threaded barrels accept 1-1/4" thread-in filters

Black fold down rubber eye-cup

Blackened edges

Multi-coated lens surfaces

Available in focal lengths of 4mm, 6mm, 9mm, 12.5mm, 15mm 32mm and 42mm
